Description

[0001] The invention relates to a vehicle spoiler. Description of the state of the art

[0002] For example, JP 2014 - 084 104 A discloses a tiltable front spoiler provided on the lower side of a front bumper. The front spoiler is changed between an deployed position (an inserted state, deployment state, unfolded state) and a static stowed position (a stowed state, stowed state, storage state, retrieval state) by expanding and contracting an airbag provided between the front spoiler and a base portion of the front bumper.

[0003] If a vehicle equipped with a front spoiler according to JP 2014-084104A encounters an obstacle on the road, there is a possibility that the obstacle will affect the front spoiler's deployment position. At the moment of impact, the front spoiler and airbag will deform, and this effect will cease if the load on the front spoiler is low. However, if the load is high, the front spoiler and airbag will not deform sufficiently, and the front spoiler will be damaged.

[0004] Further vehicle spoilers in accordance with the state of the art are disclosed in DE 10 2012 020 739 A1, US 4 441 751 A, US 6 962 388 B1 and DE 199 21 480 A1. Summary of the invention

[0005] The object of the invention is to provide a vehicle spoiler that prevents damage to a front spoiler when the front spoiler is affected by an obstacle on a road.

[0006] The object of the invention is solved in each case by a vehicle spoiler with the features of the independent claims.

[0007] Advantageous further developments of the invention are set out in the dependent claims.

[0008] According to the invention, if the internal pressure of the deployed airbag increases due to contact with an obstacle on the road, the front spoiler can be retracted into a stowed state by releasing air from the airbag to reduce the internal pressure. This means that by changing from the deployed to the stowed state at the time of contact with an obstacle on the road, it is possible to limit or reduce damage to the front spoiler. The relief valve is also positioned within the airbag to be closer to a connecting element that links the airbag and the front spoiler.In the airbag, the closer the relief valve is to the connecting element that links the airbag and the front spoiler, where an external force is applied, the sooner the internal pressure changes in response to the change in the external force. Thus, since the relief valve opens immediately after the front spoiler is impacted by an obstacle on the road, the front spoiler is retracted at an early stage. Alternatively, the relief valve in the airbag can be located on the upper side. If the relief valve is positioned to protrude from the lower side of the vehicle, damage due to impact with an obstacle on the road may occur. However, it is preferable to limit or reduce the risk of damage to the relief valve caused by impact with an obstacle on the road.

[0009] Preferably, the relief valve can be arranged within a space surrounded by the front spoiler, the bottom part of the front bumper and the airbag in its deployed state.

[0010] It is preferable, since the relief valve is located within the space enclosed by the front spoiler, the bottom part of the front bumper and the airbag, to prevent foreign objects from entering the relief valve.

[0011] Preferably, the airbag can expand so that the front spoiler is brought into a deployed state (deployed state, unfolded state).

[0012] Preferably, when the airbag expands, it can press on the second end section of the front spoiler and deform the front spoiler into a deployed state (deployed state, unfolded state).

[0013] According to the invention, it is possible to obtain a vehicle spoiler that limits damage to the front spoiler when the front spoiler is affected by an obstacle on a road. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EXAMPLES OF EXECUTION

[0015] A vehicle spoiler 10 according to an embodiment of the invention is based on Fig. 1 to Fig. 4B explained. An arrow FR, an arrow OB, an arrow RH, and an arrow LH, as shown in the respective drawings, indicate a forward direction, an upward direction, a right direction, and a left direction, respectively, as a vehicle width direction of a vehicle 12 to which the vehicle spoiler 10 is applied. The vertical and longitudinal directions, as well as the vehicle width direction, correspond below simply to the respective arrow directions described above.

[0016] First, the structure of the vehicle spoiler is explained. As in Fig. As shown in Figure 1, a front bumper 14 is provided in a front end section 12A of the vehicle 12 along the vehicle width direction. The front bumper 14 is attached to the side of the vehicle body by fasteners (not shown).

[0017] The front bumper 14, for example, is formed using resin, and its cross-sectional shape along the longitudinal direction of the vehicle is generally a U-shape, open at the rear of the vehicle (not shown). The front bumper 14 has a front wall section 14A, which serves as a design surface, an upper wall section 14B, which is bent towards the rear of the vehicle from an upper end section of the front wall section 14A and is attached to a side of the vehicle body, and a lower wall section 14C ( Fig. 2), which is bent towards the rear of the vehicle from a lower end section of the front wall part 14A.

[0018] The front wall section 14A is formed along the vehicle's width and has a gently chamfered curved surface that extends slightly towards the front of the vehicle. A front radiator grille 18 is provided in a central part of the front wall section 14A in the vehicle's width direction. Furthermore, outer end sections of the front wall section 14A are formed to extend along the side parts of the vehicle in the longitudinal direction, and rear end sections of the front wall section 14A form wheel housings 17.

[0019] As in Fig. As shown in Figure 2, the lower wall section 14C, which serves as a base section of the front bumper 14, forms a horizontal wall surface towards the rear of the vehicle. A plate-shaped front spoiler 20, made of resin, extends along the vehicle width direction from the lower wall section 14C towards the lower side of the vehicle. In a front view from the front of the vehicle, a central section 20A of the front spoiler 20 has a generally rectangular shape, and a right end section 20B and a left end section 20C, which extend continuously from the central section 20A towards the two end sides, are trapezoidal in shape, with the width decreasing in the vehicle width direction towards the outer sides (see Figure 2). Fig. 1) The front spoiler 20 according to this embodiment is able to switch between a retracted state (retracted state, extended state) (see Fig. 2) and a stowed state (storage state, storage state, recording state) (see Fig. 3) to change (to be adjusted). In the deployed state, the front spoiler 20 is in place (extended, unfolded) to be generally perpendicular to the lower wall section 14C of the front bumper 14, pointing towards the lower side of the vehicle. In the stowed state, the front spoiler 20 is stowed to be generally horizontal along the lower wall section 14C. When the front spoiler 20 is placed (dropped) into the deployed state, airflow under the vehicle floor 12 at the front of the vehicle is restricted by the front wheels 15 (see Fig. 1).

[0020] Fig. Figure 2 shows a sectional view of the front spoiler 20 in its installed state. The front spoiler 20 has a front surface section 22, which forms a design surface, a plurality of engagement claws 24 provided in the front surface section 22 on the upper side of the vehicle, and a connecting section 26 provided on the front surface section 22 on the lower side of the vehicle. The front surface section 22 is designed such that, from the front side, the central section 20A has a generally rectangular shape, and the right end section 20B and the left end section 20C have a trapezoidal shape, the width of which decreases in the vehicle's width direction towards the outer sides. Furthermore, in a sectional view in the vehicle's width direction, the front surface section 22 is designed to be able to bend from a generally straight shape into a generally L-shape (see Figure 2). Fig. 3) The multiple engagement claws 24 are provided for each of the central part 20A, the right end part 20B, and the left end part 20C, and the engagement claws 24 project towards the upper side of the vehicle from an upper end of the front surface part 22. When the engagement claws 24 are inserted into and engage with holes formed in the lower wall part 14C of the front bumper 14, the front spoiler 20 is attached to the front bumper 14 on the upper side of the vehicle. Meanwhile, the connecting part 26 is configured to have a triangular cross-section that projects towards the rear of the vehicle from the front surface part 22, and an airbag 40, as described below, is attached to a pointed portion (end portion) of this projecting section.

[0021] Fig. Figure 3 shows a cross-section of the front spoiler 20 in its stowed state. In the stowed front spoiler 20, the front surface section 22, which extends from the engagement claws 24 towards the lower side of the vehicle, is curved towards the rear of the vehicle and extends continuously towards the rear. A lower surface of the front surface section 22 (the front surface in the deployed state) is a flat surface that forms almost the same plane as a lower surface of a rear edge section 28, which serves as a mounting component for the airbag 40.

[0022] As described above, the front spoiler 20 according to this embodiment is made of resin and is formed in the mold in its stowed state when it is formed. This means that the front spoiler 20 is formed in a state in which the front surface section 22 is curved in a side view. Therefore, in the front spoiler 20, the front surface section 22 has a generally straight shape when a compressive force is applied to the connecting part 26 in the direction of the lower and front sides of the vehicle, and when the compressive force on the connecting part 26 is released, the front surface section 22 returns to its original curved state due to a restoring force.

[0023] As in Fig. 2 and Fig. As shown in Figure 3, the airbag 40 is an airbag connected to the lower wall section 14C of the front bumper 14 and the front spoiler 20, and has the function of causing the front spoiler 20 to be deployed by its expansion, and of causing the front spoiler 20 to be retracted by its contraction. As shown in Fig. 4A and Fig. As shown in 4B, the airbag 40 has a central airbag 40A corresponding to the central part 20A of the front spoiler 20, a right airbag 40B corresponding to the right end part 20B, and a left airbag 40C corresponding to the left end part 20C.

[0024] As in Fig. As shown in Figure 2, there are a number of mounting holes 42A (see Figure 2). Fig. 4A) in the airbag 40 on the rear and upper sides of the vehicle, and fastening claws 14D, provided in the lower wall section 14C of the front bumper 14, are inserted into the fastening holes 42A. Then, when the areas around the fastening holes 42A are held by the rear edge section 28, which is a separate component from the front bumper 14, the airbag 40 is connected to the front bumper 14. Furthermore, the airbag 40 is connected to the front spoiler 20 when a fixed end 42B on the front and lower sides of the vehicle is attached to the connecting part 26 provided on the front spoiler 20. A method for connecting the airbag 40 to the front spoiler 20 can be any method that uses, for example, a screw, a rivet, and an adhesive. This also applies to a method for connecting the airbag 40 to the front bumper 14.

[0025] As described above, the expansion of the airbag 40, which is connected to the lower wall part 14C of the front bumper 14 and the front spoiler 20, is arranged by the front spoiler 20 through the lower wall part 14C on the rear side of the vehicle and the upper side of the vehicle (see Fig. 2) Furthermore, by contracting the airbag 40, it is arranged in a folded position between the front surface part 22 of the front spoiler 20 and the lower wall part 14C of the front bumper 14 (see Fig. 3).

[0026] As in Fig. 4A and Fig. As shown in Figure 4B, pipe sections 46 and corresponding discharge valves 50 are provided on the upper side of the vehicle for the center airbag 40A, the right airbag 40B, and the left airbag 40C. The pipe sections 46 are arranged in a right-hand position in the center airbag 40A in the vehicle width direction, in an inner (left-hand) position in the right airbag 40B in the vehicle width direction, and in an inner (right-hand) position in the left airbag 40C in the vehicle width direction. A pipe 56, extending from a control valve 52 described below, is connected to each of the pipe sections 46 ( Fig. 2).

[0027] As in Fig. 2, Fig. 4A and Fig. As shown in Figure 4B, the discharge valves 50 are generally located in the central portions of the center airbag 40A, the right airbag 40B, and the left airbag 40C, positioned along the front side of the vehicle in the vehicle's width direction, where a connecting part (the attached end 42B) is located, which is connected to the front spoiler 20. Furthermore, in a sectional view of the airbag 40 in its deployed state, the discharge valves 50 are arranged in a space enclosed by the front spoiler 20, the lower wall section 14C of the front bumper 14, and the airbag 40 (as shown in Figure 4B). Fig. 2 is shown).

[0028] The release valve 50 is designed to open when the internal pressure of each airbag 40 exceeds a predetermined value. Specifically, if the internal pressure of the airbag 40 is affected by an obstacle on the road (for example, an obstacle X that is in Fig. (as shown in Figure 2) when the front spoiler 20 increases the airbag's internal pressure, the release valve 50 opens to reduce the airbag's internal pressure. Furthermore, the release valve 50 does not open if the airbag's internal pressure increases due to wind pressure absorbed by the front spoiler 20 while the vehicle 12 is in motion. This means that, in this embodiment, the predetermined value at which the release valve 50 opens is set to a value greater than the airbag's internal pressure increased by wind pressure absorbed by the front spoiler 20. As described up to this point, in this embodiment, the release valve 50 does not open due to wind pressure, but rather at the time of an impact with an obstacle on the road.

[0029] As in Fig. As shown in Figure 2, the airbag 40 is connected to the control valve 52 via the line 56. Furthermore, the control valve 52 is connected to a pump 54 via the line (pipe) 56. The control valve 52 and the pump 54 are electrically connected to a control unit 60, and the control unit 60 controls the opening and closing of the control valve 52 and also drives the pump 54. In this embodiment, when the control unit 60 opens the control valve 52 and also drives the pump 54, the airbag 40 is inflated; in other words, the internal pressure of the airbag 40 is increased (see Figure 2). Fig. 2) Furthermore, if the control unit 60 opens the control valve 52 while the pump 54 is not operating (is stopped), the airbag 40 is compressed; in other words, the internal pressure of the airbag 40 is reduced (see Fig. 3) In the front spoiler 20 according to this embodiment, since the front surface section 22 receives (absorbs) a restoring force that causes it to return to the bent state it was formed in, the airbag 40 is only inflated by opening the control valve 52. Then, when the control element 60 closes the control valve 52, the internal pressure of the airbag 40 is maintained. This means that the deployed and stowed states are maintained.

[0030] The following explains the operation and effects of the vehicle spoiler.

[0031] While the vehicle 12 is traveling at high speed, the airflow beneath the vehicle is restricted because the front spoiler 20 is deployed (extended, unfolded) on the lower side of the vehicle, thus reducing lift and improving driving stability. Conversely, when the front spoiler 20 is extended on the lower side of the vehicle, the clearance to the road surface is reduced, making it more susceptible to interference from an obstacle on the road. Consequently, in this embodiment, the front spoiler 20 changes between the deployed and retracted states depending on the vehicle speed. Simultaneously, the front spoiler 20 changes from the deployed state to the retracted state if it is affected by an obstacle on the road while in the deployed state. The operations are explained below.

[0032] An operational mode is a mode in which the front spoiler 20 is changed from the stowed state to the deployed state by a control function implemented by the control unit 60. In this embodiment, the operational mode is executed when the control unit 60 determines that the speed of the vehicle 12 exceeds a predetermined value (for example, 60 km / h).

[0033] In particular, it opens in the stowed state, which is in Fig. As shown in Figure 3, the control element 60 actuates the control valve 52 and also drives the pump 54, thereby sending air into the compressed and folded airbag 40. The internal pressure of the airbag 40 then increases, and the airbag 40 expands. Accordingly, a compressive force is applied to the connecting element 26 of the front spoiler 20 on the lower and front side of the vehicle, creating a generally straight shape for the front surface section 22. This means that the front spoiler 20 is in the deployed state shown in Figure 3. Fig. Figure 2 shows that when the control unit 60 closes the control valve 52 and also stops the drive of the pump 54, the deployed state is maintained. Since the front spoiler 20 is in the deployed state, airflow under the vehicle 12 is restricted, thereby reducing lifting forces and improving driving stability.

[0034] A stowage mode is a mode in which the front spoiler 20 is changed from the deployed state to the stowed state by a control function implemented by the control unit 60. In this embodiment, the stowage mode is executed when the control unit 60 determines that the speed of the vehicle 12 is less than a predetermined value (for example, 50 km / h).

[0035] In particular, in the deployed state, which is in Fig. As shown in Figure 2, when the control element 60 opens the control valve 52 while the operation of the pump 54 remains stopped, air is released from the expanded airbag. As described above, in the front spoiler 20 according to this embodiment, since the front surface section 22 receives a restoring force that causes it to return to the bent state formed at the time of molding, the airbag 40 is compressed only by opening the control valve 52. Then, when the internal pressure of the airbag is reduced and the airbag 40 is compressed, a pressure force applied to the connecting element 26 of the front spoiler 20 on the lower and front side of the vehicle is released, and the front surface section 22 returns to its original bent state. This means that the front spoiler 20 is returned to the stowed state shown in Figure 2. Fig. Figure 3 shows that when the control unit 60 closes the control valve 52, the stowed state is maintained. Since the front spoiler 20 is moved to the stowed state, a distance from the road surface is ensured, thus preventing any collision with an obstacle on the road.

[0036] A deformation operation is an operation for changing the front spoiler 20 from the deployed state to the stowed state when the front spoiler 20 in the deployed state is affected by an obstacle on a road.

[0037] The deformation operation is carried out independently of a control system by the control unit 60.

[0038] In particular, it has an effect in the deployed state, which is in Fig. Figure 2 shows that when the front spoiler 20 of the vehicle 12 is affected by the obstacle X while the vehicle is moving, an external force is applied to the connecting part 26 of the front spoiler 20 to the rear of the vehicle, increasing the internal pressure of the airbag 40. This is because the external force is applied to the airbag 40 from the attached end 42B. The release valve 50 then opens, and the internal pressure of the airbag 40 decreases. At the same time, the front surface part 22 of the front spoiler 20 bends as the airbag 40 contracts. This means that the front spoiler 20 changes from its deployed state to its stowed state.Then, since the external force continues to act on the connecting part 26 to the rear of the vehicle until the influence of the obstacle X ends, the discharge valve 50 remains open in the front spoiler 20 and the change to the stowed state of the front spoiler 20 continues until the influence of the obstacle X ends.

[0039] As described above, in this embodiment, when the vehicle is in motion and the front spoiler 20 is in the deployed position, the front spoiler 20 is not changed to its stowed position by wind pressure. However, if it is affected by an obstacle on the road, the front spoiler 20 is changed to its stowed position. Thus, even if the front spoiler 20 is affected by an obstacle on the road while in its deployed position, it is possible to limit damage to the front spoiler 20.

[0040] In this embodiment, as in Fig. Figure 2 shows the release valves 50 in the airbag 40 located on the upper side of the vehicle. However, the arrangement of the release valves 50 is not limited to this.

[0041] For example, in a modification 1, as in Fig. As shown in Figure 5, a relief valve 50 is provided in an airbag 40 on the lower side of the vehicle.

[0042] Furthermore, in a modification 2, as in Fig. As shown in Figure 6, a relief valve 50 is provided in the middle of a line 56 that connects an airbag 40 and a control valve 52. In modifications 1 and 2, as in this embodiment, it is possible to limit damage to a front spoiler 20.

[0043] In this embodiment, a front spoiler 20 is provided. The front spoiler 20 is located on the lower side of the front bumper 14 and can be adjusted between an deployed position, in which the front spoiler 20 is positioned on the lower side of the vehicle, and a stowed position, in which the front spoiler 20 is stowed under the front bumper 14. According to this embodiment, the front spoiler 20 is a plate-shaped resin component. Because its plate-shaped surface is curved, the lower end section of the front spoiler 20 moves towards the rear and lower side of the vehicle, thus achieving the stowed position. Furthermore, in this embodiment, the airbag 40 is connected to the lower wall section 14C of the front bumper 14 by the front spoiler 20.When the airbag 40 expands, the front spoiler 20 is moved into the deployed position, and when the airbag 40 contracts, the front spoiler 20 is moved into the stowed position. In this embodiment, relief valves 50 are provided to reduce the internal pressure of the airbag 40 if the internal pressure of the airbag 40 increases due to an impact with an obstacle on a road containing the front spoiler 20.

[0044] According to the vehicle spoiler 10 in this embodiment, in a case where the internal pressure of the deployed airbag 40 increases because an obstacle on the road affects the front spoiler 20 in its deployed state, it is possible to change the front spoiler 20 to its stowed state by releasing air from the airbag 40 to reduce the internal pressure. This means that by changing from the deployed state to the stowed state at the time of impact by an obstacle on the road, it is possible to limit damage to the front spoiler 20.

[0045] Furthermore, according to this embodiment, the vehicle spoiler 10 has the following characteristics with regard to an arrangement of the relief valves 50.

[0046] Initially, according to this embodiment, the relief valves 50 are provided in the airbag 40 on the upper side of the vehicle. If the relief valves 50 are provided in the airbag 40 to protrude on the lower side of the vehicle, the relief valves 50 can be damaged by an obstacle on the road. However, according to this embodiment, it is possible to limit damage to the relief valves 50 due to an obstacle on the road.

[0047] Secondly, in the installed state, the relief valves 50 are arranged in the space enclosed by the front spoiler 20, the lower wall section 14C of the front bumper 14, and the airbag 40, according to this embodiment. Because the relief valves 50 are arranged within this enclosed space, it is possible to prevent or limit the ingress of foreign matter, such as dust and rainwater, into the relief valves 50.

[0048] Thirdly, in this embodiment, the relief valves 50 are located closer to the connecting part (the fixed end 42B) that connects the airbag 40 and the front spoiler 20. In the airbag 40, the closer the relief valves 50 are to the connecting part (the fixed end 42B) that connects the airbag 40 and the front spoiler 20, where an external force is applied, the sooner the internal pressure changes in response to the external force. Thus, in this embodiment, since the relief valve 50 opens immediately after an impact by an obstacle on the road, the front spoiler 20 is retracted to its stowed state at an early stage.

[0049] The front spoiler 20 according to this embodiment is made of resin, and its lower end section, because the front spoiler is curved, moves towards the rear and upper side of the vehicle. However, the material for the front spoiler 20 is not limited to this. For example, a material that does not allow bending, such as a hard resin, can be used. In such a case, by providing a hinge in the front spoiler at one upper end, it is possible to move the lower end section towards the rear and upper side of the vehicle.

[0050] Furthermore, according to this embodiment, the airbag 40 is divided into three areas in the vehicle width direction, but the number of subdivisions and their arrangement are not limited thereto.

[0051] Furthermore, according to this embodiment, a relief valve 50 is arranged in each part of the airbag 40 (the center airbag 40A, the right airbag 40B, and the left airbag 40C), but the invention is not limited thereto. For example, a plurality of relief valves 50 can be provided in one airbag, or one relief valve 50 can be arranged in the plurality of airbags. Furthermore, the number of relief valves 50 arranged in each airbag can be changed.

[0052] The embodiment of the invention is explained above; however, the invention is not limited to the foregoing description. It is evident that, in addition to the foregoing description, the invention can be implemented in various modifications.

[0053] A vehicle spoiler is provided, comprising a front spoiler (20) located on the lower side of a front bumper (14), an airbag (40) connected to a base part of the front bumper and the front spoiler, which, by expanding, causes the front spoiler to be placed in a deployed state, and, by contracting, causes the front spoiler to be placed in a stowed state, and a relief valve (50) which reduces the internal pressure of the airbag when the internal pressure of the airbag increases due to an impact on an obstacle on a road with the front spoiler.
